Labor Services

Wissota Rering
All you have to do is pull the engine out and give us a call. We will disassemble clean and inspect every piece of your engine, from carb and ignition integrity, to camshaft-head combination, to rod and main bearing clearances. We will then contact you with parts options. After the cleaning and inspection, we check your mains for size and straight. We then verify piston to wall clearance, and hone block to a 600-grit finish.

Your crank will get checked for straight and size before giving it a high performance polish. We will check valves for straight and clearance before doing a performance valve job with standard valve angles. Springs will be closely inspected for height, squareness, pressure, and any signs of heat, before heads can be assembled according to cam size.

After the final cleaning, the engine will be assembled with the degreeing of your camshaft. The engine will then be spun up on our sim test machine to verify cranking compression, lifter-pushrod rotation, rocker arm oiling, oil pressure, cranking rpm and amperage, plug seal, and crank oiling. The final step is to dress your engine using quality Corteco (Detroit) high performance gaskets.

Policies / Warranty

Here at Ateco Engine and Dyno Shop, we want you to know exactly what to expect when you trust us with your marine and automotive engines. Find our shop policies and limited warranty below.

Ateco Engine Purchase Policy

The estimate you receive from ATECO for your engine build is an estimate only and it is based solely on the original parts and labor list. Any deviation from the estimated parts and labor will affect your estimate. Additional requested labor will be performed at the shop hourly rate and additional requested parts will be added accordingly. If ATECO does not rebuild your engine, tear down and inspection fees will apply at the listed hourly shop rate.

ATECO can accept all major credit cards for your engine purchase. We require 75% nonrefundable deposit to begin your work and an additional 15% at the time of assembly, with the final payment due upon completion.

Projects not paid in full within 15 days of completion will be assessed an Interest Charge of 2% of the balance, per month. After 30 days from completion, the customer will be liable for additional Storage fees of $15.00 per day for machine work and engines. Boats will be charged a monthly storage fee of $4.95 per foot, beginning the first day of each month it is stored.

After 1 year from completion date, property with an unpaid balance will be considered to have been abandoned and eligible for re-sale in order to recover all balances due. Any funds received from the sale that are above the balance, interest, storage fees and sales expenses will be held as “credit” toward future work for the customer.
